Data confidence 85 high
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Triplet states of aromatic molecules of the anthracene type in Langmuir-Blodgett films are investigated. It is established that the principal channel for the relaxation of T 1 states is bimolecular triplet-triplet annihilation. The observed nonexponential decay kinetics of delayed annihilation fluorescence is discussed within the formal-kinetic and percolation models.
